Nothing's more frustrating than a lighter that won't cooperate. Before you bin it, check these five common causes.
1. Air in the Fuel Tank
When air gets trapped in a refillable butane lighter, it disrupts gas flow and produces a weak flame that dies instantly.
The fix: Bleed the tank before refilling. Press the refill valve until the hiss stops completely. Fill upside-down, pressing firmly for 5–10 seconds. Wait 2–3 minutes before lighting.
2. Worn or Dirty Flint
If your lighter sparks but doesn't catch, the flint is probably too short or clogged. Spark collection lighters rely on flint striking a wheel to generate the ignition spark.
The fix: Replace the flint. If the wheel feels gritty, clean it with a dry brush or compressed air.
3. Clogged Jet Nozzles
Flame and Inferno lighters use precision nozzles. Dust, lint, or low-quality butane can clog them.
The fix: A short burst of compressed air straight down the nozzle. Never push a needle, pin or wire into a jet — it scratches the precision-machined opening and ruins it. If air doesn't clear it, purge the tank and refill with triple-refined butane to prevent buildup.
4. Flame Adjustment Too Low
Most refillable lighters have a flame adjustment dial marked with + and −. If it's been knocked to minimum, the flame barely appears.
The fix: Turn toward + one increment at a time until you find a stable height.
5. Fuel Valve Fault
If nothing else works, the valve itself might be faulty. Less common with quality lighters but it happens.
The fix: Use the warranty if available. For budget lighters, it's time for an upgrade — browse our full collection.
Prevention Beats Repair
Three habits: use quality butane (triple-refined minimum), bleed before every refill, and keep the nozzle clean. For a full service routine, see How to Clean a Lighter.
